Try dropping simultaneously two sticks into a flowing river, one near the edge of the river and one near the middle. Which one travels faster? Why?
Let us consider the fall of a pole vaulter as a
projectile once he releases the pole. The pole has
a lake of 15 8 feet and once the athlete releases
the pole he will find a mattress 2 feet high, 10 feet
wide and 16 feet long, which protects him in the
fall.
If an athlete lets go of the pole when it was 13.7 ft
above the ground with a speed of 15.7 ft/s at an
angle of 73 degrees.
Enter the horizontal distance that the athlete will
travel with the indicated conditions, add the units

A motorcycle daredevil plans to ride up a 2.00 m high 26.0° ramp, sail across a 10-m-wide pool filled with hungry crocodiles, and land at ground level on the other side. He has done this stunt many times and approaches it with confidence. Unfortunately, the motorcycle engine dies just as starts up the ramp. He is going 14.9 m/s at that instant, and the rolling friction of his rubber tires is not negligible. Assuming that the local acceleration due to gravity is -9.80 m/s2, calculate the landing point (in m) relative to the 10.0 m edge of the pool. (-1.0 m means he was 1.0 m short and in the pool, +1.0 m means he landed 1.0 m past the edge). The coefficient of rolling friction for rubber on ramp is 0.02.

- When the red kangaroo of Australia is moving at full speed, it can bounce at a speed of 8.5 meters per second, at an angle of 45 degrees above horizontal.

The ball follows the standard path of a projectile, first rising as it passes over the net, and then descending. The opponent receives the volleyball 1.1 seconds later at the same height (2.4 metres above the ground), and at a horizontal distance of 13.5 metres from the server. Answer the following questions assuming there is no effect of air resistance. When the ball was received by the opponent, the horizontal component of velocity (in m/s) was? The vertical component of velocity at take-off and impact (in m/s) can be solved by recognizing that the vertical component of velocity at the point of maximum height in the trajectory of motion is (in m/s)?arrow_forwardActivity 2.

- You are working as an expert witness for the defense of a container ship captain whose ship ran into a reef surrounding an island. The captain is being charged with intentionally running the ship into the reef. In discovery, the following information is correct: The ship was traveling at 2.5 m/s toward the reef when a mechanical failure caused the rudder to jam in the straight-ahead position. At that point in time, the ship was 900 m from the reef. The wind was blowing directly toward the reef and exerting a constant force of 9.00 x 103 N on the boat in a direction toward the reef. The mass of the ship and its cargo was 5.50 x 107kg. During the preparation for the trial, the captain claims that without control of the direction of travel, the only choice he had was to put the engines in reverse at maximum power, such that the total force exerted by the frictional drag force of the water on the propeller was 1.25 x 105 N in a direction away from the reef. From this information, construct…arrow_forwardAn archer aims her arrow directly at the stem of a coconut hanging from a nearby palm tree in hopes of knocking it to the ground.

He is going 18.2 m/s at that instant, and the rolling friction of his rubber tires is not negligible. Assuming that the local acceleration due to gravity is -9.80 m/s², calculate the landing point (in m) relative to the 10.0 m edge of the pool.

- At t=0, a block hanging on a rope is released from an initial angle of 30 degrees to the vertical. Simultaneously, a bullet is flying in the opposite direction with an unknown velocity v. When the block reaches the lowest point of its trajectory, it collides with the bullet, causing it to become embedded inside the block and resulting in a final velocity of zero. Find the initial velocity of the bullet before collision v. arrow_forwardA diver springs upward from a board that is 2.3 m above the water.

You are watching a fancy celebration which includes fireworks. These are shot from a movable platform standing at a height of 30 m above ground.

- The average thrust created by the first stage engine of a model rocket is 50N. The rocket has an average weight of 10N with a burn time of 2 seconds.

What is the closest value of the magnitude of the velocity of the cannonball at its peak.arrow_forwardAn old Biblical story tells of David, a small warrior engaged in man-to-man combat with Goliath, a much larger adversary. In the story, David uses a sling to increase the speed of a projectile (in this case a rock), striking Goliath in the forehead and killing him. O The type of sling often used in such combat consists of a long strip of cloth with a pouch halfway down its length. The rock is positioned in the pouch, with the warrior holding both ends of the sling. By whirling the sling in a horizontal circle, a warrior can release one end of the sling, thereby allowing the projectile to fly in a straight line at high speed. Historically, warriors and hunters typically used a vertical circle, but the circle used here is horizontal for simplicity. In this problem, assume that the sling, when unfolded, was roughly R = 5.54 ft in total length and that the rock weighed a half a pound. If David whirled the sling such that the sling was at an angle 0 = 4.73° below the horizontal, with what…arrow_forward
